When you say "Legit" OG is around, are you saying that based on someone saying it is "Legit" or are you saying that based on going to LA and trying the Soul Assassin cut from a truly reliable source?
I hear all kinds of people saying they have the "Real ECSD" but I have yet to see it in Canada. The only thing close to real OG or Sour is the "Larry OG" I sometimes see, it is dense and smells like Gas(In a good way) For the record the "Real OG" and the "ECSD" smell, taste and look almost like the same bud, Adam Dunn has done a few hours worth of Pod cast on the Sour and the OG trying to track the linage.
I have seen Sour on the east coast and on the west coast and I also visited a 40,000 sqft grow in Denver all 40k was Sour D, and I have yet to see anyone in Canada with it.
All I can tell you is I never see it anywhere but I have seen it. Identical structure and smells. And notably superior to all the Kushes that go around BC (Which probably was in part who grew it as he always does incredible work on a small scale all organic - never went below 24 a unit for him... anyway). Floppy like a bitch. I was told it was the SFV cut. Looked identical - have little reason to doubt. Guy was holding it tightly too.
